Intel's quad-core Kentsfield processor isn't even out yet - Intel expects to
release it in the fourth quarter of this year-but members of the
XtremeSystems forums have already gotten their hands on some engineering samples
of the chip and are overclocking the pants off them. One of these members,
who goes by the name of Stoolman, got his Kentsfield up from the stock 2.66GHz
to a clock speed of 4.8GHz. The processor did need just under 1.9V of juice
along with a healthy supply of liquid nitrogen to get to that speed, and it
stayed within a fairly chilly range of -170C to -180C (-274F to -292F.)
